\title{MBCB - Robust Multi-Array Average Background Correction for Illumina Beadarray}
\description{
  This function provides the means of using only the Robust Multi-Array Average background correction method for the Illumina platform.\cr
}
\usage{
bg.rma(pm, n.pts = 2^14)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{pm}{ The data to be background corrected. }
  \item{n.pts}{ Pertains to the specificity or accuracy of the method. 2^14 is the default. }
}
\value{
  A list with two values:
 \describe{
    \item{ex.rma:}{A vector containing the background-corrected values.}
    \item{para:}{The statistical summary of the computation.}
 }
}
\note{
  This method does not make use of negative control beads.
